The Claim
Acute hyperosmotic stress in HL-60/S4 leukemia cells is associated with increased transcript levels of replication-dependent histone genes, and this increase is likely due to disruption of the histone locus body leading to aberrant polyadenylation of normally stem-loop-terminated histone mRNAs.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When HL-60/S4 leukemia cells are exposed to acute hyperosmotic stress, the amount of RNA transcripts from replication-dependent histone genes increases as a result of altered RNA processing caused by disruption of the histone locus body.

Acute hyperosmotic stress in HL-60/S4 leukemia cells is associated with increased transcript levels of replication-dependent histone genes, likely due to disruption of the histone locus body leading to aberrant polyadenylation of normally stem-loop-terminated histone mRNAs.
When cells are suddenly dried out, the inside of the nucleus becomes too crowded and disorganized, causing a key structure that protects histone RNA to fall apart. Without this protection, the RNA gets a fake tail that it shouldn't have, making it look like there is more of it than there really is.
What the research says
1 studyStudy: The transcriptome of acute dehydration in myeloid leukemic cells.
When leukemia cells are dried out in the lab, they start making more of a specific type of RNA that helps build DNA — and this shouldn’t normally happen. The study shows this weird increase happens, which matches what the claim says.
